Study on the Combustion Kinetics of Rice Straw

The project investigated the combustion process of rice straw together with its kinetics characters using thermodynamic method.The rice straw was burned in air at the heating rate of 20 ℃/min,30 ℃/min,40 ℃/min.The final temperature was up to 800℃.From the plot of TG and DTG,the researchers has studied the influence of heating rate and temperature on the combustion process and built a kinetic equation of the reaction.The kinetic parameters of this kind of rice straw were obtained by Freeman-Carroll method.The combustion mechanism suggested will theoretically support the design of the boiler with rice straw as fuel.
